Hey guys.I just did a tutorial to help a dude out on Blender Artist. Thought some of you may be interested. The tut is about using the particle/hair system to grow multiple objects on the surface of another. In this case Sprinkles on a donut.  :)

Cool tutorial, Cybermonk.   mmm... doughnut...

I always wanted to try something like this.  Plus, you've given me some ideas for future projects where I can employ this technique, and change the instances to real items.  I usually go with the multi-duplicate meshes way.  This will be much more efficient.

What was the hiccup in the icing selection?

Was it because you decided to turn down the weights to zero, and then paint in only a line of weight-mapping?

Did this hinder going back to 100% full weights on the vertex group, and did you undo your weight painting first?

Nonetheless, thank you for the tutorial.

I think it was because I was in edit mode because when I went to object mode they showed up. That wasn't the smoothest tutorial for sure. I had just come back from the dentist and I wasn't tracking to strait. :)

I just tried it again. I change the weight an reassign the vertex group and check it in weight paint mode. It definitely changes the weight. You have to unselect the vertex group under the particle system tab density and reselect it.t doesn't want to update automatically. Weird.
